Prior to this patch only one "mlx5" thermal zone could have been
registered regardless of the number of individual mlx5 devices in the
system.
To fix this setup a unique name per device to register its own thermal
zone.
In order to not register a thermal zone for a virtual device (VF/SF) add
a check for PF device type.
The new name is a concatenation between "mlx5_" and "<PCI_DEV_BDF>", which
will also help associating a thermal zone with its PCI device.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
